No one is safe during Antonio Brown's revenge tour—including his own team. 

On Wednesday, AB posted a letter sent to him by Raiders general manager Mike Mayock to his Instagram story. In the letter, Mayock notifies Brown that he's being fined for missing mandatory training sessions.

"When your own team want to hate but there's no stopping me now," Brown wrote. "Devil is a lie. Everyone got to pay this year so we clear." 

Early into this year's training camp, Antonio Brown was placed on the non-football injury list due to frostbit feet. Later, he filed a grievance with the NFL's new helmet policy, and he announced that he would retire if he didn't get to wear his preferred helmet. Although coach Jon Gruden supported AB's plight, Mayock wasn't amused by the antics. 

"You all know that AB is not here today. So here’s the bottom line: He’s upset about the helmet issue. We have supported that. We appreciate that. But at this point, we’ve pretty much exhausted all avenues of relief," Mayock said told reporters after a mandatory practice in August. "So from that perspective, it’s time for him to be all in or all out. OK? So, we’re hoping he’s back soon. We’ve got 89 guys busting their tails."

After being called out by Mayock, AB returned to team activities, but not before AB's boss hit his pockets for missing a series of practices. The letter shows that Brown is being fined for $13,950, in addition to the $40,000 he was fined for missing a training camp practice on August 18.
